Abstract
A dual-intake fan which is a so-called sirocco fan used for venting air is disclosed. The fan has a structure in which a portion of an exhaust outlet is formed to be inclined while the centers of a scroll housing and an impeller are disposed to be eccentric so that noise can be reduced while air flow can be effectively guided by the scroll housing to the maximum extent and the air flow rate can be increased. The fan includes an impeller on which a plurality of blades are installed for rotating so as to create air flow, and a scroll housing formed so that the air drawn in through an air inlet by the impeller can be guided along a gradually expanding passage of the scroll housing, and the lower portion of an exhaust outlet is composed of at least one incline formed to be inclined upward toward any one side. In addition, the rotation center of the impeller and the center of the air inlet are disposed to be eccentric.
